Structure for improving handle loosening force of automobile steering column

Abstract

The invention relates to the technical field of automobile steering column structures, in particular to a structure for improving a handle loosening force of an automobile steering column. A cam clamping structure and a handle stand bar are fixed to the end, matching a climbing cam, of a handle. A sliding pair I is fixed on the front surface of a cam bottom plate; a sliding pair II is fixed to thelower side edge of the cam bottom plate, a clamping foot is fixed to the side edge of the lower left corner of the cam bottom plate. The sliding pair I is composed of a circular truncated cone and three climbing bosses fixed to the surface of the circular truncated cone, a through hole is formed in the circle center of the circular truncated cone, and a mounting hole and a climbing notch are formed in the cam clamping structure. The sliding pair II is a U-shaped block with a concave structure at the bottom; and the handle stand bar is in contact with the bending part of the bottom of the U-shaped block. According to the invention, the sliding pair II is newly designed; under the condition that the locking force of the handle is basically unchanged, the loosening force of the handle is greatly increased, the requirements for the locking force of the handle and the NVH performance of a system are met, and the requirements of part of customers with high requirements are met.

Description

technical field [0001] The invention relates to the technical field of automobile steering column structure, in particular to a structure for improving the release force of an automobile steering column handle. Background technique [0002] In order to meet the driving experience of drivers of different sizes and heights, the steering column of an automobile is usually designed with a two-way or four-way adjustment mechanism to adjust the orientation of the steering wheel. The driver can realize the movement and fixation of the mechanical adjustment mechanism through the switch handle. The size of the adjustment force of the handle has an impact on the driver's feel and driving safety. In order to ensure that the handle is easy to adjust, usually the locking force of the handle should not be set too large. At the same time, in order to ensure that the handle will not change suddenly due to vibration or slight collision when the handle is opened during normal use of the car,...

AI Technical Summary

Problems solved by technology

When the handle locking force meets the requirements, the release force will be small; if the handle release force requirements are met, the handle locking force will be greater than the required value, resulting in the problem that it is difficult to meet both the feel and safety, and some parts cannot be satisfied.
